Bone Mineral Density (BMD / DEXA)

Bone Mineral Density (BMD) testing, also referred to as a DEXA (or dual energy x-ray absorptiometry), is an x-ray procedure that measures the density of your bones. As we age, our bones naturally become thinner, less dense and more prone to injury. Early detection of the loss of bone mass is critical, as loss can often happen without any signs or symptoms until a fracture (break) of the bone occurs.

The results of BMD testing will help your doctor to determine the strength of your bones. A BMD test diagnoses osteoporosis (reduction in density of bone), shows the effectiveness of treatment for osteoporosis, and assesses the risk of developing fractures. The results are graphed and compared to a population at peak bone mass (young normal), as well a population that is matched to your age and gender.

When you arrive at MMI for your BMD test, you will be asked to complete a history form. You will then be required to lie still on an imaging table while an x-ray scanner passes slowly over you. We will measure the bone density in both your hip and lower spine. The amount of radiation used is minimal and is considered to be very safe.  For duration & test preparation instructions, please see instructions here.
